Based on the production and the enzymatic activity of recombinant proteins from Pichia pastoris with different fermentations,the fermentation factors of human butyrylcholinesterase were optimized.On the basis of single factor experiment,the conditions were optimized by response surface methodology,those were:4.8d,13.90% of methanol and 2.1% of glycerol.The yield of human butyrylcholinesterase was 368.2mg/L.The study provided a reference for industrial production of human butyrylcholinesterase.
